ClearSign Technology Achieves Key Milestone in Full-Scale Field Demonstration

SEATTLE, Feb. 17, 2015 /PRNewswire/ -- ClearSign Combustion Corporation CLIR, and Aera Energy LLC announced today that project objectives of a field demonstration of Duplex™ Technology in a Once-Through Steam Generator (OTSG) have been achieved. The Enhanced Oil Recovery (EOR) steam generator, located at Aera's Belridge field outside Bakersfield, CA, was tested at a firing rate of 42.5 MMBtu/hr.

Begun during the fourth quarter of 2014, ClearSign's technology met the San Joaquin Valley Air Pollution Control District's regulations under Rule 4320 requiring NOx emissions of 5 PPM (corrected at 3% O₂). These results were achieved without major modifications to the burner or the need for costly Flue Gas Recirculation (FGR). During testing, Aera's OTSG unit continued to supply steam at the capacity and quality required for oil field operations.

ClearSign plans to conduct additional testing at firing rates up to 62.5 MMBtu/hr. The objective of the tests is to continue to validate the environmental and operational benefits of ClearSign's Duplex Technology.

"The success of this field demonstration with Aera Energy represents a major milestone in ClearSign's commercialization efforts," said Stephen E. Pirnat, ClearSign Chairman and CEO. "We look forward to continuing to work with Aera and others in the oil and gas industry to accelerate the adoption of what we believe will be truly game-changing technology."
